Important Belgian mailservers becoming a spamrelay for infected clients of their ISP
Last week we wrote that some mailservers from Big Belgian ISP's were being identified by a honeypot network. Some of them were not yet identified as spammers worldwide. This is becoming the case. It becomes urgent now to do something.
please participate at this network - this is another proof that we need more honeypots to find problems before they escalate - if only administrators would DO something.
1. 220.127.116.11 Proximus
The second server 18.104.22.168 Chello.be
3. Tele2 22.214.171.124
4. 126.96.36.199 Brutele
And they all seem to have been used the last day in a spamstorm.
Maybe the days that you don't filter outgoing mail on virus, malware and pure spam are over, because otherwise you will become a relay for the botnets inside your network.
